Suppose you wish to determine if the mean IQ of students on a certain campus is different from the mean IQ in the general population, 100. To conduct this study, you obtain a simple random sample of 90 students on this campus, administer an IQ test, and record the results. The mean IQ of the sample of 90 students is found to be 106.5 with a standard deviation of 13.1. Complete parts (a) through (c) below, Click the icon to view the t-distribution table. (a) Construct a hypothesis test Ho: =Ho versus H: u# Ho for uo = 102, 103, 104, 105, 106, 107, 108, 109, 110, and 111 at a = 0.05 level of significance. Determine the test statistics for 4n = 102, 103, 104, 105, and 106. to =0 to =0 to =D Ho = 102 Ho ㅋ 103 Ho = 104 Ho = 105 Ho = 106 (Round to two decimal places as needed.)
